Ket's Weekly(ish) Anime Recommendation!

So I just pre-ordered Darker than Black: Ryuusei no Gemini. I +++LOVE+++ this series to no end. And Hei. Yeah, especially Hei.

So in honor of that, the weekly(ish) anime recommendation goes to Darker than Black!

The stars above the Tokyo sky are no longer real. With the disappearance of the sky and the appearance of Hell's Gate, a new breed of human has arrived: Contractors. Empowered with supernatural abilities they are employed by organizations and governments to wage a new kind of war with one another. Contractors are the perfect fighters as they are devoid of the emotional attachment and judgement that inflicts humanity. One Contractor stands out - who is the enigmatic Contractor BK-201?
